3 Metre cube smoke density apparatus

Wire and cable smoke density testing box (IEC 61034, GB/T 17651)Model: 3MC

Wire and cable smoke density testing box (IEC 61034, GB/T 17651)Compliant with standards:

GB/T 17651、 IEC 61034、BS 6853、BS 6724、BS 7622

Wire and cable smoke density testing box (IEC 61034, GB/T 17651)Product advantages:

Stable performance, good data linearity and * performance!

High degree of software intelligence;

Wire and cable smoke density testing box (IEC 61034, GB/T 17651)Box:

The internal dimensions of the box are a 3-meter cube

The internal material of the box is SUS 304 stainless steel, and the external material is cold-rolled sheet with spray coating treatment

The interior of the box is treated with Teflon dark color, which can resist smoke corrosion. At the same time, during the testing process, it will not fail due to reflection

The test box is equipped with a chamber door and observation window, which can observe the state in the combustion chamber

Transparent glass plates are installed on the left and right sides of the box, and light sources and optical receiving devices can be installed on both sides respectively

The part of the box near the ground has ventilation holes to ensure balanced air pressure inside and outside the box

Wire and cable smoke density testing box (IEC 61034, GB/T 17651)Optical path data acquisition system:

Equipped with a desktop fan to evenly stir the smoke inside the combustion chamber

The top of the box is equipped with a centrifugal fan to eliminate smoke generated during testing

Remote control of surface ignition device to ensure the safety of testing personnel

Equipped with a combustion testing bracket and stainless steel alcohol tray;

The light source is a 2896K color temperature incandescent lamp. This test light source is controlled by a constant current source and has higher stability;

The light source is a silicon photovoltaic cell, equipped with a cosine calibration device and a color filter. Through this measure, a higher degree of human eye matching can be achieved;

Standard transmittance, using a 19 cabinet floor installation method, with built-in touch screen computer and printer.

Wire and cable smoke density testing box (IEC 61034, GB/T 17651)Optical technical parameters:

The constant current source can adjust the color temperature coefficient of the light source. Through the current adjustment mode, the color temperature of the light source can be changed, and the standard required color temperature value of 2896K can be adjusted;

Using a constant current source to control the light source, compared to constant voltage mode, the data is more stable and reliable;

Automatically obtain optical gear with an accuracy of 0.1%;

V (λ)Matching error: f1≤4 %， The overall linear accuracy is 1%.
